About the Book

Excerpt from Mines and Mining in Eastern Ontario

These shafts cannot all be operated at present for want of power, which will be remedied in the near future.

The main lode of shafts 1, 2, 3, and 4 can be traced feet, and the south lode can be traced an equal distance.

Notwithstanding the large number of shafts, drifts and levels, there are some lodes not yet touched.

The air compressor is a frame building 140 Air x 60 feet and contains cross-compound air Compressor. Compressor with inter-cooler and after cooler and condenser, 185 horse power with all' receivers and air line from air receivers to the various shafts. High pressure steam cylinder, 125 pounds; low pressure steam cylinder, 25 pounds; high pressure air cylinder, 85 pounds low pressure air cylinder, 20 pounds; two return tubular boilers in separate rooms with electric damper regulators, large water tank, gallons capacity for coolers.

The company own a most admirable water Water power at Deer Lake, a distance of two and Power. A half miles from the mine. Two splendid dams have been built at the foot of the lake. The large dam is 80 feet long, 12 feet high, 13 feet thick at base and 6 feet at top. It is built of concrete and cement masonry. The other dam has a timber slide 20 feet wide for use of lumbermen and also a sluice gate to admit water to the ticom pipe 7 feet square. It is contemplated to install a large air compressor and bring air to the mine through a lo-inch wrought iron pipe which will then supply power for the whole mine.

The saving caused by utilizing this magnificent water power can be partly appreciated when it is learned that cords of wood are needed at the mine for power and b eating purposes.

Mr. Kerr's plan is to have ample stamp capacity in his mill and power cheap enough that the lowest grade ores can be so thoroughly treated at a low cost that practically all the gold will be extracted from the ore and thus make mining of all the ores profitable. In other words it is not his policy to rush the ores through without the most thorough treatment, which is necessary where power is expensive.
